Hi guys, I am trying to bring a lemmy instance up but I have no idea why it freezes on "building lemmy"

I wrote a small guide here. https://lemmy.death916.xyz/post/3068

But suffice to say their docker compose sux and requires some tweaking. I got mine running behind nginx proxy manager on a remote host

Thanks! I just tried the docker-compose.yml you shared and I am getting the follwoing error:

ERROR: The Compose file './docker-compose.yml' is invalid because:
Unsupported config option for networks: 'lemmyinternal'
Unsupported config option for services: 'pictrs'

If you're not using arm remove the arm tags. Not sure about the network issue as u should be able to declare networks in compose easily. Id check if some formatting got messed up in copying it over as the yaml is usually whitespace sensitive. Is there more to the pictrs error because that image is pretty basic and jus pulls it doen

I added the version line and it did the trick

version: "3.7"

nice glad to hear it.

are you using nginx? I am trying with caddy (because I already use it with other apps) but I can't access, do you have some idea how I could debug where the issue is?

ya i used nginx proxy manager. you have to put some custom locations in and passthrough some headers for reverse proxy to work.

I gave up to publish it and am trying now just run locally to see what's going on. And still I can't.

I am out of ideas :(

I get this error: When I try to access http://localhost:1236

instead of hostnames try and use an ip for everything. if not im not sure sorry

Don't be sorry friend, you are helping and you are awesome for that :)
